Safety Precautions and Maintenance

FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE

FOLLOWING WHEN SETTING UP AND USING

THE MULTISYNC LCD COLOR MONITOR:

•DO NOT OPEN THE MONITOR. There are no user serviceable parts inside and opening or removing covers may expose you to dangerous shock hazards or other risks. Refer all servicing to qualified service personnel.

•Do not spill any liquids into the cabinet or use your monitor near water.

•Do not insert objects of any kind into the cabinet slots, as they may touch dangerous voltage points, which can be harmful or fatal or may cause electric shock, fire or equipment failure.

•Do not place any heavy objects on the power cord. Damage to the cord may cause shock or fire.

•Do not place this product on a sloping or unstable cart, stand or table, as the monitor may fall, causing serious damage to the monitor.

•When operating the MultiSync LCD monitor with its AC 125-240V power supply, use a power supply cord that matches the power supply voltage of the AC power outlet being used. The power supply cord you use must have been approved by and comply with the safety standards of your country. (Type H05VV-F should be used in Europe)

•In UK, use a BS-approved power cord with molded plug having a black (5A) fuse installed for use with this monitor. If a power cord is not supplied with this monitor, please contact your supplier.

•Do not place any objects onto the monitor and do not use the monitor outdoors.

•The inside of the fluorescent tube located within the LCD monitor contains mercury. Please follow the bylaws or rules of your municipality to dispose of the tube properly.

•Do not bend power cord.

•Do not use monitor in high temperature, humid, dusty, or oily areas.

•If glass is broken, handle with care.

•Do not cover vent on monitor.

Immediately unplug your monitor from the wall outlet and refer servicing to qualified service personnel under the following conditions:

•When the power supply cord or plug is damaged.

•If liquid has been spilled, or objects have fallen into the monitor.

•If the monitor has been exposed to rain or water.

•If the monitor has been dropped or the cabinet damaged.

•If the monitor does not operate normally by following operating instructions.

•If monitor or glass is broken, do not come in contact with the liquid crystal and handle with care.

•Allow adequate ventilation around the monitor so that heat can properly dissipate. Do not block ventilated openings or place the monitor near a radiator or other heat sources. Do not put anything on top of monitor.

•The power cable connector is the primary means of detaching the system from the CAUTION • power supply. The monitor should be installed close to a power outlet which is easily accessible.

Handle with care when transporting. Save packaging for transporting.

Image Persistence

Image persistence is when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided.

To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

As with all personal display devices, NEC Display Solutions of America, Inc. recommends displaying moving images and using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

FOLLOWING WHEN YOU POSITION THE MONITOR:

•For optimum performance, allow 20 minutes for warm-up.

•Adjust the monitor height so that the top of the screen is at

or slightly below eye level. Your eyes should look slightly downward when viewing the middle of the screen.

•Position your monitor no closer than 16 inches and no further away than 28 inches from your eyes. The optimal

distance is 20 inches.

•Rest your eyes periodically by focusing on an object at least 20 feet away. Blink often.

•Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen.

•If reflected light makes it hard for you to see your screen, use an antiglare filter.

•Adjust the monitor’s brightness and contrast controls to enhance readability.

•Use a document holder placed close to the screen.

•Position whatever you are looking at most of the time (the screen or reference material) directly in front of you to minimize turning your head while you are typing.

•Get regular eye checkups.

Ergonomics

To realize the maximum ergonomics benefits, we recommend the following:

•Use the preset Size and Position controls with standard signals.

•Use the preset Color Setting.

•Use non-interlaced signals with a vertical refresh rate between 60-75Hz.

•Do not use primary color blue on a dark background, as it is difficult to see and

may produce eye fatigue to insufficient contrast. Cleaning the LCD Panel

•When the liquid crystal panel becomes dusty or dirty, wipe gently with a soft cloth.

•Do not rub the LCD panel with coarse or hard material.

•Do not apply pressure to the LCD surface

•Do not use OA cleaner as it will cause deterioration or discoloration to the LCD

surface. Cleaning the Cabinet

•Unplug the power supply.

•Dampen a soft cloth with water and a neutral detergent. Gently wipe the cabinet then dry gently with a soft cloth.

NOTE: Many plastics are used on the surface of the cabinet. DO NOT clean with benzene, thinner, alkaline detergent, alcoholic system detergent, glass cleaner, wax, polish cleaner,soap powder, or insecticide. Do not touch rubber or vinyl to the cabinet foralongperiodoftime.Thesetypesoffluidsandfabricscancausethepainttodeteriorate, crack or peel.

*1 Interpolated Resolutions: When resolutions are shown that are lower than the pixel count of the LCD module, text may appear different. This is normal and necessary for all current flat panel technologies when displaying non-native resolutions full screen. In flat panel technologies, each dot on the screen is actually one pixel, so to expand resolutions to full screen, an interpolation of the resolution must be done.

NOTE: Technical specifications are subject to change without notice.
